Phonak Retention lock for standard (xS) or power (xP) receiver wire - bag of 10
Bag of 10
These flexible pieces of plastic attach to the end of the receiver wire via a looped end.
Phonak recommend using the retention lock for a more stable positioning of the receiver wire in the ear canal.
On the end of the receiver wire, near to the dome there will be a number and either xS or xP printed. For the purposes of choosing the retention lock, ignore the number. If you see 'xS', you will need to choose Standard. If you see 'xP' you will need the Power option.
If you have a Marvel or Paradise Phonak product, you will need the Phonak Retention locks for SDS 4.0 receiver wires.
